Good tire size for 18x9 Rims

[rblcollee]

Thinking of getting 18x9 rims but not shure of what size tire to get.

i have 265/40/18 on my car now....and they fit and look great....might go slightly wider on the rear next time...275 probably, but 265 is right at home

Ok thanks! I was thinking about 275/40/18

Doesn't the 265 number represent how tall the tire is? I thought that the 40 refered to the width of the tire.

265 would be the width, 40 would be the sidewall ratio (heigth), and 18 is the rim diameter.

255s up front and 275 on the rear are popular. I'm running 275/40r18s all the way around without problems...

Here is some info I posted in another thread.........

A tire's numbers tell you the following: Section Width/Aspect Ratio Internal Construction Rim Diameter Service Info

Example: 295/35R19
Section Width = 295mm
Aspect Ratio = 35%
Internal Construction = R for Radial
Rim Diameter = 19"

To calculate the overall height you do the following:

Height of tire = (2 x sidewall) + rim diameter

Sidewall = ( Section Width/25.4) x (Aspet Ratio/100)

Since the section width is in mm we need to convert to inches, so we divide by 25.4
The aspect ratio is a percentage so we divide by 100

We can simplify the equation as:

Sidewall = (section width x Aspect ratio) / 2540

So the height of the tire becomes [2 x ((section width x Aspect ratio) / 2540)] + rim diameter

Ex.

Height = [2 x ((295 x 35) /2540)] + 19 = 27.13

275/40/18 falkens all around with 35mm offset. No problems.http://forums.stangnet.com/attachment.php?attachmentid=43463&d=1142809813
